| Abstract: |
| In order to reduce the influence of uneven pressure distribution on the rubber hose quality，the design of extrusion die for the outer layer of rubber hose was optimized.Lining was added on the back cover of the extrusion die head which reduced the effect of the most uneven part of pressure distribution on the extruded rubber hose.In addition，a ring shape rubber storage tank was equipped at the extrusion die，which allowed the all direction extrusions of rubber into the die and eliminated the influence of pressure on the outer layer thickness.The optimized die was analyzed by using the ANSYS/Polyflow software and the reliability was tested. |
